Subject: [PATCH v2 3/7] ARM: tegra: Add SATA and SATA power to Jetson TK1 device tree

This enables the integrated SATA controller on the Tegra124 system-on-chip
on the Jetson TK1 board and adds regulators for the onboard Molex connector
commonly used to power SATA devices. The regulators are marked always-on
since they can be used for other purposes than powering SATA devices.

Signed-off-by: Mikko Perttunen <mperttunen@...dia.com>

v2:
- added target-v5-supply and target-12v-supply
- made sata power not always-on
